A display device comprising channels (30, 30', 30'') containing an ionizable gas (33), and walls of the channels (30, 30', 30'') being provided with row electrodes (31, 32) for selectively ionizing the ionizable gas (33) during operation. The display device is further provided with an electro-optical layer (35) and means for activating said electro-optical layer (35). The display device is characterized in that the ionizable gas (33) contains a carrier gas and an additional gas, said additional gas comprising deuterium or deuterium hydrogen, or hydrogen and a further gas having a higher molecular weight. Preferably, helium or nitrogen is used as the carrier gas, and the additional gas comprises deuterium or deuterium hydrogen, or hydrogen and nitrogen, or hydrogen and xenon. |
